This is best read as a prequel to the bear shifter "Ever Afters" series starting with Rites of Spring. It lays some important ground work and doesn't work so well as a standalone - the cliffhanger for one (which annoys the living out of me) but it's not a humdinger, more a promise of what's to come.....
I love PNR, but no so much the "witchy" sides, but Clementine had me in this book, the insta-love could be forgiven for the page count and the bear-brother's sister, 'Vangie is a tad on the awesome-sauce side.
So, not knowing the fate of Clayton, I need to crack on with Houston's book....
